SWINGING LAVATORY Filed March 18, 1929 s sheets-sheet s Patented Nov. 17, 1931 UNITED STATES EARL G. WATROUS, F CHICAGO, ILLINOIS SWINGING LAVATORY Application filed March 18, 1929. Serial No. 348,055.

This invention is for swinging or tilting lavatories or wash bowls such as are adapted for use in limited spaces and which are particularly intended to be enclosed in a wall pocket or cabinet. Heretoiore bowls of this character have been used which were emptied by being tilted or swung up so that the contents would overflow into a hopper placed to receive the same. However, such hoppers 1U are apt to become foul and are unsanitary on account of sediment clinging tothe sides thereof. y

In the present invention I provide a swinging or tiltable bowl which has a permanent outlet connection to the discharge pipe so` that when the bowl is raised the contents will ilow out through such connection and discharge pipe. Other Jfeatures of the invention are the provision of an outlet or drain 2U through one of the pivot or hinge members and constructingv the lavatory so that the outlet also serves as an overflow, and in order to regulate the discharge automatic means are provided for tilting the bowl, said means being timed in accordance with the capacity of the discharge. p Y The objects of this invention are to provide an improved swinging or tilting lavatory which is constructed to operate in a sanitary manner; to provide a lavatory having the features above indicated and having such other improvements and novel details of construction as will appear more fully from the following specification. In the accompanying drawings illustrating this invention s Figure 1 is a front view of the lavatory shown in position in a recess 'in a wall or wall cabinet, the lavatory being shown in lowered position with thecabinet door open; Figure 2'is a vertical sectional view taken onthe line 2-p-2 of Figure 1; y p

Figure 6 is an enlarged sectional view of the combined pivot and drain outlet.

In the particular arrangement shown in these drawings, the wall 7 is provided with a recess 8 for receiving the lavatory, this recess 55 being preferably enclosed by a cabinet 9 having-a door 10. The bowl or lavatory 11 which is mounted in the cabinet may be formed of any suitable lmaterial but is preferably formed of porcelain or the like and is provided with anoutlet hole or orifice l2 leading troma point adjacent to the top of the bowl down and through a lug or projection 13 adjacent to the bottom thereof. The outlet is continued through a. hollow trunnion 14. Y This trunnion or iitting has an integrally formed flange or fulcrum plate 15 whichris secured to the lug or projection 13 by means of bolts 16, a gasket 17 being inserted to make a tight joint, as shown in 7o Figure 6. The trunnion 14 is threaded to engage with threads in a combined wall bracketand elbow 18, this `bracket having a wall plate19 which may be secured to the wall 7 or other support by means of 75 screws or bolts 20. The main drain or outlet pipe 21 is threaded into the elbow 18 and may be provided with a trap 22 in the usual manner, this pipe leading to the sewer or other point of discharge. The trunnion 14 is somewhat loosely threaded into the ell 18 and serves not only as a discharge but also as one of the pivots upon which the bowl swings, the turning movement occurring on the threaded portion. S5 The opposite trunnion 23 is carried on a bracket 24 which is secured to the lavatory 11 in any suitable manner asby means of bolts 25. This trunnion engages with a bearing 26 which is secured to the adjacent side4 90 The bowl as thus arranged might be manually raised vto discharge the contents, but in view of the relatively small outlet such discharge movement would require care in order to prevent the water from being spilled over the back of the bowl. In order that the discharge may be properly accomplished, I provide a timed automatic discharge mechanism so that the bowl will be tipped at a Y closely proper speed to pe 1init the contents to flow out through the discharge. A cylinder 28 is pivoted 29 to the wall or cabinet-below the rear portion of the bowl and is provided with a. piston 29 having a centra-l passageway or hole 30 therethrough. Ak piston rod 31 extends through the piston and has a nut 32 at the lower end of the same which is adapted to engage with lugs 33 on the lower side of the piston. The piston rod has a valve or closure 34 secured thereto which rests on top of the pistonY and serves to close the hole 30 when in engagement with the piston. The valve 34 has a small hole or Vbypass 35 therethrough, the size of which may be yadjusted by ascrew 36, as shown in Figure 5. The valve 34 has outwardly extending projections 37 which fit 1ithin the cylinder. A springr33 is interposed between these projections and the cap 39 of the cylinder,1the arrangement being suoli that the spring tends tohold the valve and piston in normally lowered position. rllhe cylinder is provided with any suitable liquid such as oil which coacts with the piston and valve yfor regulating the movement thereof. The' cap 39Qhas a packing gland or `bearing 40 for the piston rod 31. The Yupper end of the lrod is bent to form a. hook 41 which engages with a bearing 42 in the bracket 24, this bearing being slight-- Vly at the rear of 'the trunnions as will be readily seen from Figure 5.

An operating ever 43 is pivoted at 44 on a fulcrum plate 45 Vwhich is secured to the wall or cabinet by screws 46. This lever has a handle 47 at the top and a catch` or hoolr 43 at its lowervend whichis adapted to engage with the bearing 42 or other suitable Vprojection on the bracket 24. rlhe lower end of the lever has a `cam projection 49 forming a continuation ofthe catch 48 which is adapted to be engaged by the bearing 42 for returning the lever to normal position.

5 rlhe lower end of the lever is also providedV with an extension 50 ywhich is adapted to engage with the fastening plate of the bearing 26 to limit the movement ofthe lever.

The bowl 11 is preferably provided with a ledge 51 around the upper edge which pro-v jects inwardly a suliicient distance to servelras a baille or guard to prevent waterv from splashing out of the bowl and also serving as an abut-ment or guide at the back to direct the water to the outlet 12. It will also be noted that the outlet 12 is adjacent to the top ofthe bowl, although the lip or lower'edge 52 of the outlet opening from the bowl is slightly below the top of the bowl so that the outlet serves as an overflow as well as a drain. Vhile the bowl may ordinarily be manipulated by grasping the rim of the same, I have provided a hand hole 53, as shown particularly in Figure 3, which is formed in thehollow rim.

The top of the lavatory may be made straight, but in order to permit the same to be installed in a limited space with the water supply pipes arranged horizontally above the bowl, I have shown the forward portion of the bowl as being offset to clear such pipes.

The hot and cold water pipes 54 and 55 are carried up through the wall and provided respectively with laterals 56 and 57 which connect with 'the'opposite ends of the double faucet 58 which is preferably mounted on a casing 59 which encloses the laterals 56 and 57. The faucet is preferably arranged at thecenterof the'bowl and slightly above the same and is of such proportions that it is enclosed in the bowl when the bowl is in raised position.

When the bowl is to be used, the user opens the cabinet and pulls the bowl down which raises the piston rod 31 against the tension of the spring 33'in the cylinder 28. During this movement the valve 34 is raised away from the piston, thereby leaving a free passage'way for liquid through the piston as the piston is raised by the nut 32. Then the bearing 42 reaches its uppermost position, it strikes the cam 49, as shown in Figure 4, and swings the lever 43 to upright or locking position, as shown in Figure 5. The bearing then engages with vthe hook 48 and serves to hold the bowl in lowered or operative position. lVhen the bowl is to be raised or returned to the cabinet, the user pulls the handle 47 forwardly which releases the bearing 42 from the hook 48.

The spring 38 pressing down on the valve 34 causes the passageway through the piston to be closed and then moves the valve and piston downw( rdly. During this movement the liquid in the bottom of the cylinder passes through the hole 35, the sizeof which may be adjustedV by the screw 36, and this gives a restricted vdownward movement to the piston rod, and consequently a restricted tipping or tilting movement to the lavatory. rlhis retarded movement is regulated so that the lavatory will swing upwardly and the contents will 'be discharged through `the outlet without any voverflow or spilling.

Fromthis description, it will be seen that l provide a swinging lavatory which may be installed jin limited space and which will be not only eliicient in operation but of a particularly sanitary nature. However, changes may be made to adapt the same for different conditions or uses; therefore l do not wish to be limited to the 'form herein shown and described,except as specified in the following` claims, in which I claim: A
